The canister further comprising a canister bottom, immediately adjacent to the lighting canister rod, and a canister wall immediately adjacent to an edge of the lighting canister platform. The lighting canister platform is configured to elevate the transformer above the canister drain pipe in order to permit water to drain out of the canister and away from the transformer.
Abstract: A recessed light fixture can include a movably adjustable light source and a thermal management system that includes a movable first heat sink, and a second heat sink. The first heat sink is thermally coupled to the adjustable light source, and is connected to move with the adjustable light source. The first heat sink includes a plurality of spaced apart first thermally conductive elements, such as fins. The second heat sink includes a plurality of spaced apart second thermally conductive elements, such as fins, which are interlaced between the first thermally conductive elements of the first heat sink. The interlaced thermally conductive elements increase surface area and heat transfer pathway(s) between the two heat sinks, while reducing physical contact, and thus friction, therebetween when movably adjusting the light source.
Abstract: An assembly of a decorative trim on the exterior surface of a plastic cover lens of a headlamp. Locking means are molded on the outer side of the plastic cover lens, which extend out in a transverse direction (Y) pointing at an angle from the surface of the plastic cover lens.

The method comprises a step of providing a first portion of light radiation in a first incident angle range; and another step of providing a second portion of light radiation in a second incident angle range consecutive to the first incident angle range. The first incident angle range is greater than the second incident angle range viewed from a vertically downward direction of a light source emitting the light radiation, and the correlated color temperature of the first portion of light radiation is lower than that of the second portion of light radiation.
Abstract: A method for adjusting the lighting range of a headlamp in a motor vehicle, is performed with the following steps. A first coordinateis acquired that corresponds to a position of the motor vehicle. At least one image of a camera connected with the motor vehicle is evaluated so as to acquire a second coordinate that corresponds to the position of an object on a roadway in the zone ahead of the motor vehicle. A reference angle is calculated for the motor vehicle from the first coordinate, the second coordinate and a height of the camera over the roadway. The lighting range of the headlamp is adjusted based on the reference angle.
